I was able to locate a NIB RV-75 at a reasonable price and it is now part of my shack. Works like it should and I don't think that it was ever installed anywhere. Still in original box and had the temporary manual and QC tag's. I am a happy camper now. Have a great 7 line system.? Late SN TR7, L7 amp, L7PS, MN2000, RV-75, and WH7. Putting out almost legal limit on 40 meters and will be checking other bands soon.
73? Bob
